Honeygal 1 Report post Posted November 20, 2010 Noticed 2 small grey black patches on bathroom mirror after moving in for 2 months. Then realised these patches have been getting bigger and spreading. Any idea what the cause is and how to remove them? The patches are on a part of the mirror where no water touches. Share this post Link to post Share on other sites
january 0 Report post Posted November 20, 2010 Similar thing happened to me before. It could be mould, which is a sign that there's either: 1. a leak in the bathroom. 2. poor ventilation in your bathroom. Share this post Link to post Share on other sites

Honeygal 1 Report post Posted November 21, 2010 the patch comes from behind. i can see that it is not on the mirror. i was told it has to do with inferior quality of the back piece causing a chemical reaction. Share this post Link to post Share on other sites

cruise 0 Report post Posted December 20, 2010 From experience I noticed such spots tend to appear if you wash your mirror with soap / detergent. Once I stopped such cleaning agent on my new mirror I dont see it happening again. Just clean mirror with water and wipe will do. Avoid any chemical contact on mirror.
